One thing to remember when buying an LCD flat panel is the resolution. Most LCD 23" and up offer at least 1280x720 native pixel resolution. This the minimum pixel count you should look for. Some LCD's listed as 1280x768, or 1368x768 and some of the much larger LCD now offer 1920x1080 native pixel resolution but this is way above your price range. Pero kung gusto mo ang best of the best, hey!, why not.
Samsung and Phillips are very good LCD'S. Philips offer Pixel plus 3 HD and the panel resolution is 1920x1080 one of the highest resolution in the market. Samsung innovation are reaching a new heights and believe it or not, one of the most best selling HDTV here in U.S. So either way sa gusto mo you cant get no mistake. Again, resolution is the KEY. Good luck in your new system.
